The Center for Intercultural Dialogue publishes a series of short briefs describing Key Concepts in Intercultural Dialogue. Different people, working in different countries and disciplines, use different vocabulary to describe their interests, yet these terms overlap. Our goal is to provide some of the assumptions and history attached to each concept for those unfamiliar with it. As there are other concepts you would like to see included, send an email to the series editor, Wendy Leeds-Hurwitz. If there are concepts you would like to prepare, provide a brief explanation of why you think the concept is central to the study of intercultural dialogue, and why you are the obvious person to write up that concept.
